Chapter 3 Volume Management
3.1 Create Volume
• Volumes are formatted automatically when they are created. Standard, WSV, TPV, and SDV can be
accessed from the host when host affinity is set after volume creation. SDPVs can be used after volume
creation is complete and formatting is started. NAS user volumes can be accessed from the host when
NAS interface is set and shared folder is created after volume creation.
• When a volume is created manually (*1), the volume number can be specified. Note that volumes have
to be created one at a time. Multiple volumes cannot be created when specifying the volume number for
a new volume.
*1: Volumes can be created manually for WSV type volumes or when drives are selected manually to create
Standard, TPV, SDV, or SDPV type volumes.
Refer to
• When "Automatic" is selected to create a volume or when "Manual" is selected but a volume number is
not specified, the volume number is allocated when a volume is created from the smallest unused
decimal number in ascending order.
• When "Manual" is selected, create the specified number of volumes by using the maximum free space
that is available in the RAID group. In this case, inputting the volume capacity is not required. "Standard",
"WSV", and "SDPV" type volumes are created by using the maximum free space.
• This function cannot be used to create an ODX Buffer volume. Refer to
(page 662)
• The EXC set state of the ETERNUS DX, and the set states of EXC and EXCP for each volume do not
cooperate. Regardless of the set state of EXC for the ETERNUS DX, the default state of EXC and EXCP for
each volume is "Enable". Refer to
for the ETERNUS DX.
• The secondary cache (EXC or EXCP) that is being used in the ETERNUS DX can be checked. Refer to "System
Settings" in "ETERNUS Web GUI User's Guide (Operation)" for details.
• Enabling or disabling EXC for each volume can be performed with ETERNUS CLI or ETERNUS SF Storage
Cruiser.
• Enabling or disabling EXCP can be performed with ETERNUS Web GUI. Refer to
Parameters" (page 316)
• In the controller firmware versions V10L31 and earlier, "SED" indicates "Online SED".

Creating Standard, SDV, or SDPV type volumes
Detailed information on creating Standard, SDV, or SDPV type volumes is provided below.
• Volumes are created in the RAID group.
• There are two methods to select a RAID group; "Automatic" and "Manual".
• For "RAID6-FR" type RAID groups, only "Standard" volumes can be created.
• To create an SDV or SDPV, the Advanced Copy license is required. For the ETERNUS DX60 S3/DX100 S3/
DX200 S3 and the ETERNUS DX200F, a free license is registered by default.
• The following shows the conditions for creating SDPVs.
- The volume capacity must be 2TB or less
- The volume capacity must be a multiple of Snap Data Pool Element (SDPE) capacity (1GB/2GB/4GB)
(*1)
*1: The current SDPE capacity can be checked in the [Snap Data Pool] screen under the [Advanced Copy] naviga-
tion.
